Crafted from aircraft grade aluminum and fitted for most industry standard handlebars, the Lithium double clamp is a subtle yet massive addition to the Root Industries clamp lineup, becoming the first brother clamp to the AIR double clamp. Durable, sleek, and functional, this high-quality clamp will keep your compression tight and your bars straight as can be, all while maintaining Root Industries ultra light standard. The Root scooter clamp is an aluminum double clamp. Double clamps are super light weight and the choice of most pro scooter riders, whether they ride street or park. Double clamps only have 2 bolts to compress your bars around your forks so, while they are effective, a triple or quad clamp will provide more clamping power and reduce the frequency with which you will have to tighten your clamp bolts. The Root clamp was designed to work with standard outer diameter bars with a slit and cannot be modified to work with oversized bars. The Root double clamp includes standard M6 bolts, which provide adequate clamping power but can strip if overtightened. It is a good practice with any compression bolt to tighten each bolt 1/2 turn at a time, one bolt at a time, until all bolts are completely tight. The Root scooter clamp works with the following types of compression: ICS, ICS10, IHC.
